Problems solved by technology

However, the gas produced by methanol reforming includes a certain amount of impurity gases in addition to hydrogen, and proton exchange membrane fuel cells have relatively strict requirements on the purity of hydrogen gas. Therefore, the co-production technology of methanol reforming and fuel cells is not yet mature enough.

Description

technical field [0001] The invention relates to the technical field of resource integration, in particular to a combined proton exchange membrane fuel cell system based on solar thermochemical methanol reforming for hydrogen production. Background technique [0002] Since the fuel cell can be matched with the widely distributed fuel gas system at present, the fuel cell has broad application prospects in many fields, among which hydrogen is the most ideal fuel. However, when hydrogen is used as battery fuel, the safety and high cost of storing and transporting high-pressure pure hydrogen are very low, which is one of the important bottlenecks for its large-scale application. Methanol is an ideal hydrogen carrier, and it only needs to be reformed by methanol steam to achieve the purpose of hydrogen production. Conventional reforming hydrogen production requires low temperature, low cost, high hydrogen-to-carbon ratio, and is convenient for storage and transportation. Based on...
